BOTTLE AND JAR STQPPER;

SPECIFICATION forming part of Letters Patent No. 303,558, dated August12, 1884.

Application filed November 27, 1883. (No model.)

T at whom it may concern.-

Be it known that I, MARK CAMPBELL, a citizen of the UnitedStatesresiding at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Bottle-Stoppers andJar-Stoppers, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to certain new and useful improvements in stoppersfor bottles, jars, cans, &c.

The object of my invention is to provide a safe, secu're,and durablestopper for bottles and cans and other vessels, which may be securelystopped and made air-tight for the purpose of preserving fruits, acids,chemicals, and

other articles from the air. I attain these objects by means of thepeculiar arrangement and construction of the various parts of my device,which will be more fully pointed out and described in the specificationand claim,- reference being had to the drawings accompanying thisapplication and forming part of the same.

Figure 1 represents a vertical section of a jar provided with myimprovement. Fig. 2 is a side view of the stopper, the jar beingindicated in dotted lines. Fig. 3 represents the several parts of thestopper detached. Fig. 4 is a vertical section showing a modification inconstruction of stopper.

Similar letters of reference refer to similar parts in the severalfigures of the drawings.

A designates a jar or bottle, formed of glass or other suitablematerial, and having a mouth at the top, which is usually formed with anannular rib or enlargement, A. The cap B is formed to close over themouth of the jar, and may be roughened on its edge a to afford a gripfor the hand of a person turning it to open or close the jar.

D indicates a washer or plate placed under the capB. It is somewhatsmaller in size than the mouth of the bottle or jar, so that it may bepassed into it readily, and has a concavity in its under surface,forming an annular pro- -jecting edge or rim, 0. A screw-bolt, a, havinga head, F,'the latter being downward, passes up through a centralaperture in washer D into a threaded hole or recess in the cap B.

The head F forms the lowest part of the stopper, and has at its upperedge an annular recess or rabbet, b. r

E is a ring, made of rubber or other suitable flexible 1naterial,andplaced so that it rests in the recess 6 in position to be compressedbetween the parts D and F, as seen in Fig. 1,

the said recess forming a seat for the ring and serving to keep it inproper place and posi tion.

The several parts of the stopper being properly placed together andapplied to the jar, and the cap B being turned in the proper direction,the screw (1. is drawn upward, causing the parts D and F to compress theflexible ring E, which is thereby expanded laterally and closes againstthe inner surface of the neck of thejar, thus tightly closing the mouth.

It will be seen from the formation of the parts D and F that the head Fcan be drawn upward, so that its upper part enters the concavity in theplate D, if found necessary in order to compress the flexible ringsulliciently. D

In Fig. 41' a modification in construction is shown, the stopperconsisting of cap B, screw (1., with head F, ring F, and a thumb-nut, d,placed on the upper end of the screw. The cap and head are each formedwith an annular recess or rabbet to form a seat for the ring E, and thescrew a passes up through an aperture in the cap, the parts beingsecured by means of thumb-nut d, which bears on the cap, and is used incompressing or releasing the flexible ring.

I claim- The combination of the cap B, having central threaded recess,the washer D, havinga central opening, a concavity on its lower side,and a beveled edge, screw a, having head F,

that is provided with an annular recess, b,

and flexible ring E, that is adapted to be con1-.

pressed in the annular recess between the washer I) and head F,substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

MARK CAMPBELL.
